Spent over an hour this morning trying to get this game working on my domestic LAN for my two lads to play head to head. Gave up in the end. Phoned the helpful people at EA Games and they confirmed my suspicions.
I need two product CD's one for each computer on my net. (potentially another £30). This wasn't the case for previous C & C products, where you could generate a slave or 'spawn' programme on another computer on a local net.
I'm not making any judgements here, just seems to be the way software is developing nowadays vis a vis Windows XP.
